摘　　要：根据陕西省大气污染物排放标准规定,2019年7月1日起使用燃气锅炉氮氧化物浓度必须低于50mg/m3,燃油锅炉150mg/m3。此次针对双炉胆的燃油燃气蒸汽锅炉低氮改造,通过更换燃烧器加装烟气外循环的方式实施低氮改造,大幅度降低氮氧化物排放浓度至以下,符合锅炉排放标准规定,同时具备锅炉燃烧的可靠性,改造后取得了较好的成果,该技术方案及改造方法为类似项目提供了参考依据和借鉴。According to the air pollutant emission standards of Shaanxi Province,starting from July 1,2019,the nitrogen oxide concentration in gas fired boilers must be lower than 50 mg/m^(3),and in oil fired boilers,it must be 150 mg/m^(3).This time,for the low nitrogen transformation of the dual furnace oil fired gas steam boiler,the low nitrogen transformation is implemented by replacing the burner and installing flue gas external circulation,significantly reducing the nitrogen oxide emission concentration to below,in accordance with the boiler emission standards,at the same time,it has the reliability of boiler combustion and achieved good results after transformation.This technical scheme and transformation method provide a reference for similar projects.
